Proven Siemens Gamesa technology for onshore wind projects
Siemens Gamesa 4.X platform
 

The Siemens Gamesa 4.X platform leverages the knowledge acquired through the development of our latest onshore wind turbines and integrates innovative technologies to achieve higher efficiency and cost-effectiveness.

Our onshore portfolio relies on proven concepts with extensive track record in the market, such as the combination of a three-stage gearbox (two planetary and one parallel) and a doubly-fed induction generator, which offer the higher levels of reliability.

In addition, the inclusion of an optional premium converter allows us to comply with the most demanding grid connection requirements.


Technological highlights
Our onshore approach is focused on geared technology, in which we have extensive knowledge and expertise. The hallmarks of Siemens Gamesa turbines are: reliability, robustness and a modular, flexible design for optimum adaptation and maximization of production at any site and in all wind conditions.
Thanks to OptimaFlex technology, we go beyond the traditional off-the-shelf approach that results in products that are sub-optimal for many sites, and we deliver a uniquely tailored solution that is perfect for our customers’ specific needs. Optimized site design combined with a customizable product platform, based on flexible power rating, site specific towers and optimized BoP solutions, allow Siemens Gamesa to deliver reduced LCoE by increasing AEP while optimizing cost.
As an aerodynamic blade add-on, DinoTails® Next Generation reduces the sound power levels by using a serrated trailing edge mounted at the blade and adding finer combs in between the teeth. This world-leading noise reduction technology enables us to create value for our customers by maximizing AEP and reducing the LCoE in sites with noise constraints.
This turbine is equipped with blades made of fiberglass reinforced with epoxy. Together with the state-of-the-art aerodynamic profile, we can produce lighter blades having greater strength and improved dynamic behavior with less load transmitted to the rest of the components.
Turbine sensors continuously transmit data to our diagnostic centers, enabling the early detection of anomalies and preventing potential failures. By analyzing vibration patterns we can optimize your service plan and anticipate repairs before serious damage occurs.
